Answer:
$290
Step-by-step explanation:
We are told that 1 out of 5 buyers change to a more expensive sofa than the one in the sale advertisement.
Now we are told that the advertised sofa is $250 and the more expensive sofa is $450.
Thus;
P(x) for expensive sofa = 1/5
P(x) for sofa in sale advertisement = 4/5
Thus, expected value is;
E(X) = (1/5)450 + (4/5)250
E(x) = 90 + 200
E(x) = $290
With these values x = 14.
In order to find this, we must note that LM will be half of KM (since L is the midpoint). Because we know this, we also know that we can multiply LM by 2 and set equal to KM.
2LM = KM
2(2x + 4) = 5x - 6
4x + 8 = 5x - 6
8 = x - 6
14 = x
Answer:
in ur 4figure table fine tan 45 and mutiple it by 3 and find sin 60 and mutiple it by 4 ur answer mutiple it by what u got in tan 45 mutiple by 3
fin cos 30 and mutiple by 2 and sin 30 mutiple by 3 mutiple ur answers together
then finally what u got for the first on subtracted from ur second answer
P = 2(L + W) ....this is the perimeter of a rectangle
P = 40
L = 5
40 = 2(5 + W)
40 = 10 + 2W
40 - 10 = 2W
30 = 2W
30/2 = W
15 = W <=== ur answer is 15 ft
Answer:
It is the experimental condition.
Step-by-step explanation:
In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.
The 8 hours of sleep, which creates the difference in the experiment between the control group and the test group, is the experimental condition.
The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.
I hope this answer helps.
